SPECIFICATION forming part of Letters Patent No. 539,961, dated May 28,1895.

Application filed October 13, 1894. Serial No. 525,784. (No model.)

To aZZ whom it may concern:

Be it known that I, STERNE RUSSELL, a citizen of the United States,residing at Naugatuck, in the county of New Haven, State of Connecticut,have inventeda new and useful Improvement in Atomizers, of which thefollowing is a full, clear, and exact specification. My inventionrelates to improvements in atomizers hereinafter fully set forth.

The object of my invention is to produce an atomizer of simpleconstruction, all the parts of which being readily accessible forcleaning, and which will, by mechanical acmixing air with the liquid inthe atomizing tube just prior to its being ejected therefrom as isordinarily done.

My invention is illustrated by the accompanying drawings, in which-Figure 1 is a perspective side elevation of the complete. apparatus.Fig. 2 is a vertical section of a cap and supply and atomizing tubes.Figs. 3 and 4 show details of the apparatus in perspective, each beingenlarged with relation to the other views. Figs. 5 and 6 are sideelevations of atomizing and supply tubes, respectively, partly insection.

A is a liquid receptacle made substantially,

E and I) are two tubes proj ecting from said cap. The tube D connectsthe interior of the receptacle with the source of air pressure, whichmay be a suitable bulb or other form of pump as desired.

H is a detachable supply tube adapted to conduct liquid from theinterior of the receptacle A to the tube E.

F is an atomizing tube, preferably detachably connected to the tube E asshown. This tube F is provided with onlya single conduit through whichliquid alone passes.

To cause the liquid to atomize without mixing air with the same, as isordinarily done, I insert into the outer end of the tube F a core G, thesurface of which is provided with one or more grooves therein cut on aspiral as shown. By creating pressure within the receptacle by means ofthe bulb or pump re- .ferred to, liquid is forced up through the supplytube H through the tube E and thence through the atomizing tube F. Thearrangemeut of the grooves in the core G at the forward end of saidatomizing tube F, gives to the liquid as it is ejected a rapid twist sothat when it is ejected itbreaks or separates into fine drops. The sizeof these drops may be materially reduced by utilizing a cap K, adaptedto slide over the end of the tube F, the said cap Kbeingprovided with aperforation centrally located in the end thereof. In order to regulatethe amount of liquid to be forced through the said atomizing tube andthe grooves in the core, I provide any suitable means in the lower endof the tube H whereby the capacity of the said tube may be 6:; regulatedor varied, for it has been demonstrated that to facilitate the moreperfect effectiveness of the device, the quantity of liquid supplied tothe atomizing tube should be proportionate to the size and shape of thegrooves formed in the core G.

One form of device for varying the capacity of the supply tube is shownin Fig. 4., which consists in a core I having a longitudinal groovetherein, the said core being adapted to fit Within the lower end of thesupply tube, and the groove permitting theliquid to pass thereinto. Ifdesirable a cap J having perforations of suitable size may besubstituted in place of the core I. r

The particular advantage of this instrument is the simplicity of itsconstruction and operation. It being composed of parts which aredetachable, every portion of the device is readily accessible forcleaning; a feature 8 5 which is most desirable in case it should beused as a physicians instrument, in which case the parts are allsubjected to an antiseptic wash. In operation it will be observed thatthe liquid is not mixed with air during the process of atomizing, as iscommon in the ordinary atomizer, but, on the contrary, the atomizing isaccomplished entirely by the mechanical construction at the forward endof the atomizing tube F.

In the modification. shown. in Fig. 5, the atomizing tube F illustratesthe desirability of having the tube detachable, so-that tubes of variousshapes may be substituted in place of the ordinary straight tube ifdesirable.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. In an atomizer, an atomizing tube having IOO a single conduittherethrough, a core located in the forward end of the said atomizingtube, said core being provided with one or more spiral grooves in itssurface for the purpose described, with a supply tube leading into theinterior of the receptacle, and adapted to conduct liquid containedtherein to the said atomizing tube, and with means for affording airpressure Within the liquid receptacle.

2, In an atomizer, an atomizing tube having a single conduittherethrough, a core located in the forward end of said atomizing tube,

said core being provided with one or more spiral grooves in its surface,a centrally perforated cap at the forward end of said atomizing tube,with a supply tube adapted to conduct the liquid from the interior ofthe receptacle to the said atomizing tube, and with means for forcingthe liquid through said supply aud atomizing tubes.
